Field Museum scientists discover new dinosaur

Paleontologists at the Field Museum have discovered a new dinosaur that walked North America about 100 million years ago.

The giant predator was found in Cedar Mountain, Utah in 2008.

It was more than 30 feet long and weighed more than four tons.

The discovery helps researchers fill in a 30-million year gap in the fossil timeline of giant meat-eating dinosaurs in North America.

Siats meekerorum — named by the scientists after a man-eating monster of legend from the region’s Ute Indian people and the Meekers, a museum donor family from Evanston — helps flesh out what has been a skeletal picture of North American wildlife in the tens of millions of years before Tyrannosaurus rex was the dominant predator.
